Application filed December 27, 1818. Serial No. 189,211.

To all whom it may concern:

Be it known that I, \VILLIAM JAMES Hossnr, a British subject, residing at Sturgeon Falls, Province of Ontario, Dominion of ing the drum for rotation.

While the invention is in some respects of general application, the preferred embodiment hereinafter disclosed comprises a drum open at both ends and adapted to receive blocks of wood at one end and to deliver them, after barking, through theother end, the separated bark being liberated throu h openings in the side of the drum and t e .blocks of wood under treatment being pethe following detailed description, which is to be taken in conjunction with the accompanying drawings, wherein-- Figure 1 is a side elevation of the barking apparatus;

Fig. 2 is an end elevation of the same showing the discharge end;

Fig. 3 is a section on the line 3-3 of Fig. 1;

4 is an elevation of one of the drum supports;

Fig. 5 is a detail'showing one of the drum guides; and

Fig. 6 is a section through the annular sprocket whereby thedrum is rotated.

In the drawings, the drum 1, wherein the blocks of wood are tumbled, is of cylindrical shape and comprises a plurality of flanged rings 2 to which are secured angle bars 3 havlng inwardly projecting flanges which give to the inside of the drum an irregularity of surface suflicient to cause progressive cascading of the pile of wood therein when Y the drum rotates. These bars 3 are spaced far enough apart to form long, narrow slots in the wall of the drum through which the bark detached from the blocks may escape.

The drum is arranged for rotation in a tank 4having an outlet conduit 5 covered by a grating 6 and controlled by 'a valve 7, so that, when desired, the tank may be filled with water and the blocks of woods thus be periodically immersed in the water as the drum rotates. Preferably, the drum carries flights or combs 8 secured to its'periphery and arranged to sweep the curved concentric bottom of tank 4 and lift therefrom over the edge 9 of the tank such detached bark as has passed through the slots of the drum into the tank. The bark so delivered over the edge 9 of the tank can then be carried away bya suitable traveling conveyer 10.

The means for supporting and driving the drum (and it is to this that my present invention is particularly directed), comprises a framework having uprights 11, top members 12, and cross-beams 13, and some at least of the cross-beams 13 are provided with drum supports 14' which may be in the form of downwardly extending rigid brackets, as shown, bolted to the cross-beams 13 and provided with rollers 15 to engage a ring 16 encircling the drum, the engagement taking place at a point above the median line of the suspended relation to tank 4: but free to ro-' tate in the tank when desired,

The drum supports above described may be arranged in pairs, as shown (Fig. 3), and four such pairs with their cooperating rings 16 will serve to support a barking drum of usual dimensions.

As a means for rotating the drum in its supports, there may be provided a sprocket or annular rack 19 encircling the drum near ward pull on the two supporting brackets 14 of each pair. As a means for steadying the drum during rotation, guide wheels 24 may be mounted on either side near the ends of the drum to engagea guide ring 25, (Fig. 5)

When the drum Is in action, the blocks of wood to be barked are delivered to the open intake end thereof by a. conveyor 26 and are delivered down a chute 27 and thereafter, because of the rotation of the drum, are caused to cascade in the drum, sliding over one another and thereby gradually detaching the bark which is allowed to escape through the longitudinal slots into the water tank and from there is removed over the edge 9 of the tank by the paddles or combs which periodically sweep through the water and scrape off the bottom of the tank. An end wall of planks secured to uprights 11 prevents the wood blocks from escaping at the open intake end of the drum. By the time the blocksof wood reach the discharge end of the drum the bark will have been removed from them and they may be-pe'rm itted to escape over the plank barrier 28 (Fig. 2) by which this otherwise open end of the drum is in part closed. The blocks thus 11berated fall on an inclined grating 29 where they may 'be washed off by a water spray from pipe 30 (Fig. l) and then delivered to a conveyer 31 (Fig. 2) for transportation elsewhere.

When the blocks of wood are to be barked dry, as, for instance, when they are of hemlock, valve 7 is opened to draw the water from tank 4, and, except that the blocks are not periodically immersed in water during tumbling, the mode of operation 1s essen tially that above described.

With a drum thus supported on rollers which are suspended fromabove and engaging-the rings at a point above the median line of the drum, there are no obstructions in the water tank about or behind which bark can accumulate, and by making the tank relatively shallow, as shown, and substantially concentric throughout with the drum and free from any bark-receiving corners or pockets, the combs or flights 8 0p crate with effectiveness and without substantial consumption of power in sweeping the bark from the tank and over the edge thereof for delivery to conveyor 10. p v

The drum supportin means is rugged in construction and simp e.in design, is easy to lubricate and not easily deranged, it holds the drum from swinging or jumping out'of position,-and at the same time will continue to; give reliable support and guidance even though the drum may be distorted in shapeeight to ten feet, or even more, and when such a drum is carrying its normal charge of wood, the weight aggregates many tons.

I claim: I

1. In a bark removing machine, the combination of a rotatable drum, supporting rollers on which said drum may turn, said rollers engaging the drum above its median line and suspending it from above while leaving the space beneath the drum unobstructed, and means for rotating said drum on said rollers.

2. In a bark removing machine, the combination of a drum wherein blocks of wood may be tumbled for removal of their bark, a framework above said drum, rigid means suspended from said framework and rotatably supporting said drum above its median line, and means for rotating said drum while thus supported.

3. In a bark removing machine, the combination of a rotatable drum in which blocks of wood may be tumbled for the separation of their bark, said drum having openings in its side through which the separated bark may escape from the drum, a framework, a plurality of brackets secured to said framcwork and supporting said drum above its median line, said brackets having rollers to facilitate rotation of the drum, and means for turning said drum on said rollers.

4. In a bark removing machine, the combination of a rotatable drum adapted to continuously receive blocks of wood at one end and to discharge them at the other end, said drum having bark discharging slots, a tank adapted to contain water wherein the drum may rotate, rings encirclin said drum, rollers engaging said rings a ove the median line of the drum, and rigid means supporting said rollers from above and leaving an unobstructed space beneath the rotating drum.

5. In a bark removing machine, the combination of a rotatable drum adapted to continuously receive blocks of wood at one end and to discharge them at the other end, said drum having bark discharging slots, a tank adapted to contain water wherein the drum may rotate, said tank having a concave hotand means carried by the drum for continuously removing the bark from the tank as the drum rotates.

6. In a bark removing machine, the combination of a rotatable drum adapted to continuously receive blocks of Wood at one end and to discharge them at the other end, said drum having bark discharging slots in its side, a tank adapted to contain Water Wherein the drum may rotate partly submerged to periodically submerge the Wood under treatment, said tank having a concave bottom which throughout is substantially concen trio with the drum, said tank being unobstructed from end to end, a supporting framework, rigid brackets suspended from said framework, rollers carried by said brackets, rings encircling said drum and engaging said rollers to suspend the drum therefrom, means for continuously rotating said drum on said rollers, and means carried by the drum for continuously lifting the separated bark over the edgeiof the tank as the drum rotates.

7. In a bark removing machine, the combination of a drum adapted to continuously receive blocks of Wood at one end and to dis charge them at the other end, said drum having bark-discharging slots in its side, an annulus encircling said drum and having an engageable inner periphery and means r0- tatably supporting said drum from said inner periphery, substantially as described.

8. In a bark removing machine, the combination of a drum, a tank, an annulus encircling said drum and having an engageable inner periphery and means outside of the tank and engaging and supporting the drum from such inner periphery above the level of said tank While permitting the drum to rotate on such supportin means.
